OCR command is not detecting certain terms

Hey guys, I tried to use the OCR command upon this image in order to identify text here. But OCR is not identifying SHERPA SURF SCHOOL. It is only able to identify the regions in RED. I guess it is because of the colour disparity amognst red and black layers.Any help in this regard would be deeply appreciated !!!

First extract the separate color channels,
% Extract the individual red, green, and blue color channels.
redChannel = rgbImage(:, :, 1);
greenChannel = rgbImage(:, :, 2);
blueChannel = rgbImage(:, :, 3);
threshold each one for white,
binaryR = redChannel > 200; % Or whatever value works
binaryG = greenChannel > 200; % Or whatever value works
binaryB = blueChannel > 200; % Or whatever value works
then AND the three binary images together.
finalImage = binaryR & binaryG & binaryB;
Now do the OCR.
